I'm using MATE 1.6 from the official MATE APT repo.

I've tried enabling Compiz using the following steps, based on this guide and adapted for MATE 1.6:

1. Open dconf editor


2. Go to org.mate.desktop.session.required-components


3. Change windowmanager from marco to compiz


4. Relogin

However, when I relogin, I have no window frames and no Compiz plugins. I've tried compiz --replace in a terminal, which gives no errors, only logs of it loading plugins.
